What to do if Android lies with exclamation mark? In this article, we will consider the main causes of device malfunction and ways to solve it.
The first version of the Android operating system appeared in 2008. Availability a large number functions, ease of use and low price in comparison with analogues made it affordable for a wide range of users.

Usually, the user may face such a problem when turning on (rebooting) a smartphone or tablet. If this happened to you, what can you do?
The first thing that is offered in such cases is this. To do this, you need to turn off the device, if necessary, recharge it to 100% and turn it on in the menu for developers. Since the key combination depends on the smartphone or tablet model, we recommend that you refer to the instructions. V standard case this can be done by simultaneously holding the power buttons, volume down and / or Home.
In some cases, the smartphone after this action can return to factory settings automatically, but sometimes it needs to be done manually. Remember that only buttons work in this state (you won't be able to use the sensor). You will have to use the volume keys to move up and down through the menu items. In the list, you need to select the position "Wipe data / Factory reset" with the power button or Home button, which means "delete data / reset settings" and in the next window that opens, confirm your choice.

And these are contacts, messages, photos, audio and video recordings and the programs you installed. Therefore, if you do not want the safety of your data to depend entirely on one electronic device, do backups in advance.
If you are not sure that you can cope with this task on your own, it is better to contact a specialist, because any mistake can lead to disastrous consequences.

Possible causes of the problem
Duplication of shortcuts occurs for various reasons:
- Failure due to device reboot or factory reset;
- The problem is caused by a third-party application (its incorrect configuration by the developers);
- Applications are installed twice, on internal and external memory;
- The application incorrectly duplicates information in the cache, which is why the launching icon is bifurcated;
- Unsuccessful update or firmware of the device.
Other reasons are also possible. Most often, the problem spreads to third-party applications. The icons of the standard software, as a rule, are not duplicated.
How can this be fixed
There are several ways to stop duplicating app icons on Android smartphones or tablets.
Unchecking GooglePlay
The GooglePlay service has a function that adds application shortcuts to screens in automatic mode... By disabling this feature, the user will prevent shortcuts and duplicates from being created:
In the future, apps downloaded from GooglePlay will stop creating icons.
Cleaning Launchers
Launchers are lightweight applications. Through one of them, you can eliminate the problem of duplicated icons. In GooglePlay, you need to download any launcher. To do this, enter the query "Launcher" in the search bar. When the application is downloaded and installed, you need to:
The final button for deleting settings may have a slightly different name. After this procedure, the lost phone settings will be restored, the desktop will be cleared of unnecessary shortcuts.

The cache stores temporary program files in the same-named section of the internal memory; it is used on all Android operating systems. To work with the Dalvik cache, you need Root rights... The files in this section are necessary to speed up the launch of the most frequently used applications on the device.
You can clear the cache of a smartphone or tablet using the following algorithm:
- Enter the device settings;
- Go to the "Storage" or "Memory" section;
- Click on the entry "Cache data";
- At the bottom, you will be prompted to clear the cache.

Why is this sign at the level of the smartphone network?
Exclamation point at the cellular network level
This article is not about the exclamation mark on the Wi-Fi icon. This article is not about the exclamation mark on the Wi-Fi icon in your computer. This is exactly about the exclamation mark of the signal strength of the cellular network.
On Android 5 and higher, this feature has appeared. It lies in the fact that there is no Internet on the smartphone. No mobile internet, no GPS, no Wi-Fi.
It's simple. If you connect any Mobile Internet either GPS or any Wi-Fi then that exclamation mark icon disappears.
Wi-Fi turned on exclamation mark disappeared
Turned off Wi-Fi exclamation mark appeared
There were questions, but there is no answer in Google. Well, now you already know what it is.
Internet on smartphone
Smartphones such as iPhone or Android phones Are mainly small pocket computers with mobile communication, GPS and camera. Like any other modern computer, they are a means of accessing the Internet. For many, this is their main function.
Most smartphones use two different technologies to access the internet: cellular and Wi-Fi. The advantage of the cellular network is that it works almost everywhere. You can access the internet from almost anywhere you have cellular services.
However, with most phones and in most places, you get third generation (3G) and sometimes second (2G) service, which is very slow. You can get 4G, but most of the phones that people already use do not support this signal. Moreover, 4G is widespread in a small number of cities.
Of course, Wi-Fi can be much faster, depending on the network. But it is not everywhere. Wi Fi at your home, cafe, library and office. Wai Fai severely restricts you on the terrain. You need to know the password from the Wi-Fi network. Another problem: Wi-Fi drains your phone's battery faster than 3G.
And now everyone at the exclamation point -
The green android robot no longer greets you when you turn it on, but lies accompanied by an exclamation mark.
So, if you see this picture - the android lies with an exclamation mark, then you can be congratulated, you made your first unsuccessful experiment to interfere with the software of your device. What is it, and most importantly, what to do with it and how to restore the viability of the device? The search for answers to these questions should be started, first of all, by finding out the reason that led to this state.
If you installed an incorrect program for the android, then after rebooting it will certainly delight you with an image with an exclamation mark. There is only one way out - to do hard reset by selecting Wipe data / factory reset in the engineering menu.
Entering the engineering menu, if your android "lies" is different on different smartphones on android, but the combination of home, power and volume down keys is recognized as standard. On devices with a touch home button, the combination of power and volume down keys usually goes through. The key combination suitable for your device must be pressed with your fingers and held until the service menu appears on the screen.
After the inscriptions appear, you must select the appropriate item by moving up and down using the volume rockers. After selecting this item, several lines will appear on the device screen, asking if you agree to delete all data from your device. After selecting the line yes, the device memory will be completely erased. The next step, if the device has not rebooted, automatically select the rebootsystemnow item, which indicates a system reboot. If after these operations your device has restored its working capacity, then we can congratulate you. The only drawback this method is the loss of all information - including contacts, sms, photos and downloaded applications.
However, if you regularly sync your phone with Google and remember the username and password from account then your losses will be negligible.
If the above method did not help, then you need to make a complete replacement of the software. There are two ways - the first firmware of the device using a usb cable and a computer, however, it will only help you if the “debugging by usb” function was enabled in the device settings. The second way is to update the software using a flash card through the engineering menu. Both methods are very risky and, at the slightest violation of the instructions, will lead to the complete death of the device. At this stage, you should think about whether to try to restore the device yourself or trust the professionals.
If you nevertheless decide to flash an android with an exclamation mark yourself, then you should carefully study all the information provided on the Internet on this issue. Certain types of android-devices have significant differences and features regarding the change of software. Briefly and generally describe this process, then it looks like this - you find the firmware file on the network, download it, along the way studying the reviews about this version and information on installation. After that, you decide on the method of carrying out the procedure for restoring an android with an exclamation mark.
If you chose the method using usb cable, then unpack the firmware files to the root directory of the C drive on the computer, if necessary, install the drivers for your smartphone, turn off the phone, use the key combination (usually the combination power + volume up) enter the phone into the firmware mode, connect the device via a usb cable and follow the further instructions of the program ... At the end of the process, be sure to follow hard reset device settings to standard using the recovery menu.
If you decide to resort to the second method and restore the software using the device itself and the flash card, then the steps are as follows - upload the firmware file to the root directory, insert the flash card into the phone and run it in recovery mode. After the appearance engineering menu select a recovery point using SD and wait. After the end, you also need to reset the parameters of the android device.
